In the era of technological progress, agriculture is a sector that is constantly evolving and transforming. Leading the way in this transformation is QTech Design, an innovative company that is ready to present its revolutionary Agro Projects for the fall of 2023.

These projects, aimed at solving some of the biggest challenges facing farmers, will use the latest technologies to improve the productivity and efficiency of farms. Among all these innovative projects, one stands out in particular: Frost protection system for peach, apricot and nectarine plantations.

Developed in cooperation with the agricultural trade MIKS AGRO, this system will provide farmers with effective protection of their plantations from the harmful effects of frost. Using the latest technologies and adapted to European standards, this system represents a big step forward in the fight against climate challenges and ensuring quality production.

This project was financed through the European Agricultural Fund for Rural Development, through the tender Submeasure 4.1. "Support for investments in agricultural holdings". The goal is to restructure, modernize and increase the competitiveness of agricultural holdings, including the establishment of new and/or restructuring of existing perennial plantations.

But this is just the beginning. In addition to the Frost Protection System, QTech Design plans to present a number of other innovative solutions aimed at transforming agriculture.

The fall of 2023 will be an exciting time for farmers who will have the opportunity to take advantage of these revolutionary systems. With QTech Design at the helm, the future of agriculture has never looked brighter.

Join us in this exciting new phase of agriculture and stay up-to-date on the revolutionary Agro projects that QTech Design is bringing in the fall of 2023. Together, we can reshape agriculture for a better, more sustainable future.

A new innovative project is underway that aims to develop a new solution for covering agricultural crops. The project, which is being undertaken by Qtech in collaboration with the Faculty of Mechanical Engineering and Naval Architecture from Zagreb, seeks to create a new system that will allow for a more efficient configuration of crop areas depending on production needs.

The project is still in its early stages, but the team is confident that the new system will be significantly more advanced than existing solutions on the market in terms of durability, thermal insulation, and physical resistance. In addition, the new system will be easier to assemble and disassemble and more cost-effective.

The mobile construction for crop protection will be controlled by a new software system developed by Qtech and Drvoplast. This system will allow for automatic opening and closing of the coverings depending on weather conditions and will be easily managed via mobile devices or computers.

The development of new technologies for crop protection is essential for the future of agriculture. With the global population expected to reach 9.7 billion by 2050, the demand for food will continue to increase, putting pressure on farmers to produce more with fewer resources.

That is why this open-source project needs your support. If you are a farmer, an agricultural engineer, or just someone with an interest in the future of agriculture, please consider joining this project. Your support will help ensure that this innovative new system is developed and made available to farmers worldwide.

In the orchard of the Kos family there are 1400 cherry trees, but rarely that have fruit. Those cherries that are found red they are also thick, but there are too few to go on sale with.

"Losses are almost 100 percent, what we have is for personal use. What 300 to 400 kg maximum. Of the projected, realistically projected 15.16 tons," he said Space Kos, from OPG Kos.

The Kos family has hired Qtech design to develop a pilot project for an antifrost system on 2,000 m2 of permanent cherry orchard. The pilot project defined the input parameters required for the development of a technological project for the reconstruction of a permanent plantation using a frost protection system (antifrost system).  

 

 

The system in Demerje protected the cherry at -2.2 ° C with a rainfall intensity of 2.22 mm / m2 / h of water. The maximum flow of the system was 4.74 m3 / h and an all-night pressure of at least 0.5 bar on the pulsator. The accumulation required for one day of protection was 71 m3 / h of water. Energy consumption was 0.75 kW / h, which was spent on the operation of the supply water supply

As part of Croatian forests There are several clone plantations that produce forest tree seeds, and among them is the seed clone plantation of wild cherries in the forest area. Polojac - Šartovac, nearby Kutine. The owner of the clone plantation is Hrvatske šume, Forest Administration Zagreb, Šumarija Kutina.

Qtech design has been hired to implement a pilot project of an antifrost system on 360 m2 of wild cherry in the most unfavorable location within the microclimate of plantations. The pilot project defined the input parameters required for the development of a technological project for the reconstruction of a permanent plantation using a frost protection system (antifrost system). 

 

The system in Kutina protected wild cherries at -5 ° C with a rainfall intensity of 2.8 mm / m2 / h of water. The maximum flow of the system was 1 m3 / h, which maintained a pressure of 0.5 bar on the pulsator throughout the night with the help of a free-fall water tank. The accumulation required for one day of protection was 15 m3 / h of water, and at low supply levels it was replenished from the accumulation lake by means of a pump to replenish the reservoir located at the highest point of the orchard. Energy consumption was 1.5 kW / h, which was spent on the operation of the pump to replenish the water tank. 

Within the microlocation of the system, one agrometeorological station was installed with equipment for meteorological monitoring and systemic monitoring of pressure within the water supply system (antifrost system and drip irrigation system). The agrometeorological station covers the microclimate within 3 hectares of plantations. 

 

 

The mission of FPS is to contribute to the full sustainable production of food and biosystems. The intersection of the FPS software and hardware solution allows fruit systems to maximize production by reducing costs and increasing yields. By applying this innovative technology, the FPS system efficiently collects system, weather and production data from various micro locations, and with the help of smart analytics improves production characteristics. Customer focus, continuous improvement and technical innovation of this system, position FPS as a unique market participant destined for rapid growth.
